1 Claim. 1

My invention relates to improvements in pedal mechanisms forautomobiles, the principal object in view being to provide means ofsimple form and inexpensive construction for easy application to anautomobile to operate the brakes and carburetor throttle through asingle pedal, thereby obviating fatigue on the part of the driver of anautomobile resulting from shifting the foot from one pedal to another.

Another object is to provide means of the character and for the purposeabove set forth which is safe, will not get out of order nor tire thefoot and leg of the operator.

Other and subordinate objects, also within the purview of my invention,together with the precise nature of my improvements will be readilyunderstood when the succeeding description and claims are read withreference to the drawings accompanying and forming part of thespecification.

In said drawings:

Figure 1 is a view partly in longitudinal section and partly in sideelevation of my improved pedal mechanism in a preferred embodimentthereof;

Figure 2 is a view in plan;

Figure 3 is a view in transverse section taken on the line 3--3 ofFigure 1;

Figure 4 is a view in longitudinal section taken on the line 4-4 ofFigure 2 and illustrating the manner in which the pedal is designed tobe operated.

Referring now to the drawings by numerals, according to my invention, asillustrated, a foot pedal I is provided of generally elongated oval formwith an upstanding rear end heel guard 2 for preventing the foot fromslipping rearwardly off the pedal I, said pedal also embodyin n thetransverse center thereof a depending edge ear 3 on one side and adepending lever arm 4 on the other side thereof.

A channel type bearing bracket 5 with upstanding side iianges {i isprovided for supporting the pedal I and is suitably secured to the floorI board I of an automobile, not shown, with its side flanges 5 extendingforwardly and rearwardly, said bracket having a longitudinal side slot 8therein registering with a similar slot 9 in the floor board I.

The ear 3 and lever arm 4 fit between the side flanges 6 of said bracket5 and a cross bolt I extends through said flanges and the ear 3 andlever arm 4 with a cotter pin II on one end thereof, and whereby saidpedal I is swingably mounted on said bracket for rocking movement 2about a transverse axis forwardly and rearwardly respectively, thearrangement being such that the lever arm 4 extends through the slots 8,9 a distance below the floor board I suitable for a purpose presentlyseen.

A coil spring I2 surrounds the bolt II between the ear 3 and the leverarm 4 with one end flxed in a lug I3 on said ear 2 and its other endfixed in a lug l4 on the bottom of the bracket 8, and whereby the pedalI is balanced to assume a normal intermediate position parallel to thefloor board I.

A link bar I5 extends beneath the floor board- I forwardly andrearwardly of the automobile and parallel with said pedal I, normally.The link bar I5 is provided with a central slot portion I6 into whichthe lower end of the lever arm 4 extends and is pivoted in said portionby a transverse pin II. The link bar I5 is provided with enlarged frontand rear ends II, I! longitudinally slotted, as at 20, 2|.

The front end It of the link rod I5,is operatively connected to a forkedhead 22 on a throttle control rod 23 by a cross pin 24 in said headslidable in the slot 20 of said end I9.

The rear end I9 of said link rod I5 is operatively connected to a forkedhead 25 on the front end of a brake control rod 26 of the automobile andby a cross pin 21 in said head 25 slidable in the slot 2| of said endI8.

In the normal position of the pedal, as shown in Figure 1, the cross pin24 is positioned in the front end of the slot 20 of the front end II ofthe link rod I5, whereas, the pin 21 is positioned r in the rear end ofthe slot 2| of the rear end I! of said rod. Consequently, when the pedalI is rocked forwardly, as shown in full lines in Figure l, a pull isexerted on the throttle control rod 23 for operating the usual throttlevalve, not shown, of a carburetor for accelerating the speed of theautomobile, whereas, the rear end I9 of the link rod I5 slides idly onthe cross pin 21 with no effect on the brake control rod 26. When thepedal I is rocked rearwardly, as shown by dotted lines in Figure 4, apull is exerted on the brake control rod 26 to set the brakes, notshown, and the front end I8 of the link rod I5 slides idly on the crosspin 24 and relative to the throttle control rod 23. It will of course beunderstood, that in the normal position of the pedal I and the link rodI5, the throttle and brake control rods 28, 26 are also in normalineffective position. When the pedal I is relieved of pressure of thefoot, in either its forwardly or rearwardly rocked position, the coilspring I2 will return the same and the link bar I! to normal positiondescribed, the throttle and brake control rods 23, 26 being returned tonormal in eifective position by the usual well known means.

The foregoing will, it is believed, sufllce to impart a clearunderstanding of my invention, without further explanation.

Maniiestly, the invention, as described, is susceptible of modificationwithout departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appendedclaim.

Having described the invention, what is claimed as new is:

Mechanism for operating a throttle control pull rod and a brake controlpull rod of an automobile comprising a foot pedal, means for pivotallymounting said pedal for vertical rocking movement forwardly andrearwardly, respectively, from a normal intermediate position, a singlelever arm depending from said pedal for swinging in opposit directionsby rocking of said pedal for- REFERENCES CITED The following referencesare of record in the file or this patent:
